Fits perfect. I didn't even have to drill out old brackets, just popped off rivets with a flat head screwdriver, the big screws pulled tight the warped holes for a tight fit. Don't forget the provided foam insulation!

The drill size recommended was for the new attachment screws. If you use it to drill out the existing rivets you will have to work a little to remove them as they just spin after the initial flange is cut off by the drill. My speakers could attach to the mounting bracket without using the screw clips.

Nice fit. Don't forget foam between speaker and door panel.

Made installation to the front doors of the blazer a breeze. Drilled the heads off of the factory rivits and removed the factory mount bracket with the speaker still attached. Had to pry out on the factory plastic mount with a flat blade screwdriver to stop the rivits from spinning in the door when trying to drill. Drill lightly with high speed! These lined up perfectly on the Blazer doors and allowed for simple and quick speaker installation! Thank you Crutchfield! Make sure you request these for your Blazer or S-10 truck!

Didn't need them. Factory brackets worked well with new spkers. I have an extra set laying around the garage now.

worked great easy install, purchased 4 speakers 2 front 2 rear 4 mounting brackets were shipped only needed 2 for front door speakers fit in rear doors no mods

perfect fit & free!

Great sound resonator. Easy installation and quick.

They work great, but I would have prefered holes in the plastic, that lineup with the holes in the speaker. To make speaker more stabile.

I ordered these because I bought speakers, but they didn't include these brackets. They fit right where the stock ones did,and fit the 5 1/4 speakers that the stock ones could not. They are quite pricey considering they are just plastic (hence the 4 star rating).

I did not use these to mount my polk db651s speakers to the front doors of my 99 Blazer. I instead ended up slightly modifying the OEM brackets. I was not interested in sacrificing the OEM mounts once I drilled out the pop rivets. I could have re-pop riveted them to the door, but who wants to go through all that hassel just to end up NOT using the brackets crutchfield sent you. While these looked sturdier than the OEM brackets and looked to have the mounting holes line up perfectly, I did notice some differences in how the OEM brackets was molded to fit against the door to minimize any air gaps, whereas crutchfield's bracket was completely flat and would have left gaps between it and the door (it places where the door was not flush). This could be overcome with some cushions or silicone, etc but i was not interested in the hassle. Also, you would need to make a hole for the speaker wires to come through the bracket since there were none pre-made. It was either than or having them pinched between the bracket and the door once mounted. Again, I was no interested in all the modifications I would have had to make when I had the OEM already there and required less mods for the install. I wasn't sure the benefit of a new bracket would have been great enough to warrant the install. I did keep these in case I change my mind in the future. Not a bad product, but I just decided to go a different route.

Very easy to install. Holes matched up perfectly in my '96 Jimmy. Speakers fit in perfectly.

Other than having to drill the rivits out of the old ones install was a breeze comes with everything needed!

The bracket itself fit perfect on my 97 s10, but the holes to mount the speakers on did not match up with my Infinity reference 6022 si. So i had to drill new holes... other then that good product

decently built for the price but don't easily fit the 6.5" Rockford Fosgate component speakers that i have

Very easy to install and all instructions were easily followed.

When I went to install this into my 95 S-10 found that didn't match up with existing holes, have to drill new holes behind the door panel in order to make it work. Could also fit nicer than it does.
